Description

【発明の詳細な説明】 この発明は請求の範囲第一項の導入部に記載のとくに
自動車用のラック式かじ取り機構に関する。The invention relates to a rack-type steering mechanism, in particular for motor vehicles, according to the preamble of the first claim.

いる。The rack-type steering mechanism is particularly suitable for mounting on passenger cars and microbuses. For example, a steering device known from GB 20 37 931A has a rack which is pressed by a spring-loaded pressing member in a drive pinion. As a result, the rack maintains the engaged state with the drive pinion even on a rough road, and does not generate rattling noise. Another purpose of the pressure member is to increase the inherent friction of the steering device, thereby suppressing axial vibrations of the rack and thus of the steering wheel. Both sides of a drive pinion provided at the lower end of the handle shaft are supported by roller bearings.

極度に間接的な変速機構を有するヨック式かじ取り装
置では駆動ピニオンは比較的小さい直径を有している。
従って、かじ取り負荷が高い場合、かじ取り機構は同時
に生じる捩じり及び曲げ力に耐えない。例えば高速度で
敷石の縁を踏んだ場合のような事故に類する負荷がかか
る場合は、駆動ピニオンが破損することがある。In a yoke steering system with an extremely indirect transmission, the drive pinion has a relatively small diameter.
Thus, when the steering load is high, the steering mechanism does not withstand the simultaneous torsion and bending forces. When a load similar to an accident is applied, such as when stepping on the edge of a paving stone at a high speed, the drive pinion may be damaged.

従ってこの発明は駆動ピニオンに作用する有害な曲げ
力をできるだけ低く抑えることによって、ラック式かじ
取り機構の負荷力を改善することを目的としている。Accordingly, it is an object of the present invention to improve the load force of a rack-type steering mechanism by minimizing harmful bending forces acting on a drive pinion.

る。This object is achieved by the features described in claims 1 to 4. According to the invention, the steering housing surrounding the drive pinion is formed such that the peripheral surface of the drive pinion opposite the rack is supported in the steering housing. As a result, relatively large bending forces on the drive pinion can be supported in the steering housing. This increases the breaking strength of the drive pinion for the same dimensions. It is preferred to provide a support dish in the steering housing surrounding the drive pinion at an angle of about 180 °. In this support plate, the pinion can move freely under normal running load. There is no problem in the steering operation. However, when the steering load is high, the deflection of the drive pinion has an allowable limit. Therefore, breakage of the pinion is avoided.

かじ取りハウジング４内に鋳造することも考えられる。In FIG. 1, the drive pinion 1 is mounted in a steering housing 4 via roller bearings 2 and 3. The rack 5 is engaged with the pressing member 7. A pressing member 7 under the action of the spring 6 presses the rack 5 against the teeth of the drive pinion 1. The handle shaft 8 connects a steering wheel (not shown) to the drive pinion 1. The distance between the pressing member 7 and the rack 5 can be adjusted by, for example, an adjusting plate 10. This interval can be determined by using a screw bolt.
According to the invention, a support plate 11 is mounted on the drive pinion 1 in the steering housing 4. This support plate 11 is connected to the steering housing 4 by screws 12 as shown in the figure. The support plate 11 can also be riveted or glued to the steering housing. As is evident from FIG. 2, the support plate 11 surrounds the drive pinion 1 at an angle of about 180 °. Alternatively, it is conceivable to cast the support plate into the steering housing 4 as a projection.

ト“S"を越えた後、支持皿１に当接する。駆動ピニオン

は生じない。Since the rack 5 transmits the strong impact from the steered wheels to the drive pinion 1, the drive pinion 1 comes into contact with the support plate 1 after crossing the slit "S". Since the drive pinion 1 is completely free to rotate under normal load, no friction loss occurs.
